Origami/kirigami, the ancient art of paper folding and cutting techniques, has provided considerable inspiration for structural design routes in engineering medical fields over last few decades. The practicability methods concepts origami/kirigami been demonstrated several emerging classes technologies, e.g., stretchable electronics, deformable devices, self‐assembly fabrication, etc. More more related products are produced pursuing a form better storage, deformation capacity, multifunction...
An electro-hydraulic servo pump control system (hereinafter referred to as EHSPCS) is a volume unit that highly integrated with motors, fixed-displacement pumps, hydraulic cylinders and functional valve groups. Because of its unique direct-drive mode, the dynamic performance limited, thermal power loss large, which seriously restricts improvement working quality system. To improve reduce maximum extent, multi-objective optimization design method for EHSPCS proposed by comprehensively...
Abstract Learning rate scheduling (LRS) is a critical factor influencing the performance of neural networks by accelerating convergence learning algorithms and enhancing generalization capabilities. The escalating computational demands in artificial intelligence (AI) necessitate advanced hardware solutions capable supporting network training with LRS. This not only requires linear symmetric analog programming capabilities but also precise adjustment channel conductance to achieve tunable...
An independent pump-controlled hydraulic system based on a variable speed displacement power source (VSVDPS) can eliminate throttle losses of the electric loader boom and recover gravitational potential energy. However, challenges arise in efficiently rapidly solving for optimal due to severe load fluctuations, model inaccuracies, coupling two variables. This paper proposes an energy-efficient optimization method search combined (MSCM), which leverages advantages model-based fast solution...
Abstract Human‐machine interfaces (HMIs) serve as essential channels for communication between humans and machines. However, current HMIs often require the integration of batteries, multiple sensing components, electrodes, resulting in complex configurations, limited flexibility, poor scalability. In this work, a body‐coupled mechanism employing power–frequency electric magnetic field an energy source is proposed, HMI with double spiral electrode structure (DS‐HMI) has been designed based on...
To address the performance degradation of standard linear extended state observers (LESO) caused by severe peaking phenomena with increasing system order, which compromises controller accuracy, this paper proposes an innovative output feedback using a cascaded observer structure. Through uniform exponential stability (UES) criterion, we demonstrate that proposed guarantees bounded tracking errors for states. A novel approach constructs desired load pressure from reference trajectories,...
In practical engineering, it is very difficult to obtain data on the slipper wear of hydraulic pumps, especially under high-speed, high-pressure conditions, which limits development fault diagnosis technology for pumps. At present, a test method that can accurately simulate operating state pair high-speed and conditions does not exist.

Multi-way spool valves (MWSVs) with K-shape notches (KSNs) provide advantages such as improvement of the actuator speed control, micro-action, and response performance. However, pressure drop (PD) associated energy consumption is larger MWSVs under high-pressure large-flow condition. Meanwhile, extremely complex flow coefficient multi-parameter, highly coupled KSNs are chief factors restricting flow-pressure characteristics exploration optimisation design MWSVs. To address these problems,...
A maximum power point tracking control strategy for an affine nonlinear constant displacement pump-variable hydraulic motor actuation system with parameter uncertainty, used within offshore wind turbine, is studied in this paper.
